Well, you're right; I only meant to use PCI as an example.  The main 
point is that *some* way of recording the digital stream and playing it 
back on a computer.  It might be PCI (or PCI-Express), PCMCIA, USB or 
FireWire.  An external device or breakout box that plugs in to a PCI 
card would still qualify as a PCI device for purposes of this 
discussion, since that's the interface that would be presented to the 
computer.

Which I pointed out in my previous message (just forgot the actual 
terminology).  The 'robustness rule' would seem to preclude *any* 
implementation on an 'open' hardware platform like a standard PC.  Tivo 
can do it because their devices are ostensibly locked down (let's not 
argue about the hackability of the Tivo).

Or if it's made to work only in conjunction with some kind of 'trusted 
computing' (i.e., Palladium) platform and/or proprietary DRM scheme.  
Basically, because of the robustness clause, it seems that software (or 
even firmware?) can't be part of the authorization chain, because *all* 
software can be hacked/reverse engineered.  Again, I see this as a 
problem that Microsoft *must* solve if they are going to continue to 
market MCE.  It's really just a question of whether we (the homebrew 
PVR community) will be able to leverage their solution.  Obviously the 
best scenario would be for Microsoft to shift their weight against the 
broadcast flag.  I doubt that would happen, but then again maybe MS 
thinks it's a big enough juggernaut to thumb their nose at Hollywood on 
this.

No doubt.
